monitor metered quantities of oil from
10 mm3 to 600 mm3 per lubrication pulse.
The maximum number of pulses per minute
is 4 pulses at a maximum operating pres-
sure of 40 bar.
The specifications in the “Technical data”
chapter must be adhered to.
Any other or additional usage of the flow
sensors of the GS300 series is deemed
non-compliant with the intended use.
Usage is permitted exclusively in the context
of commercial or business activity by
professional users.

2. Lubricants
2. Lubricants
2.1 General information
Lubricants are used specially for specific
applications. To fulfill the task, lubricants
must meet various requirements to varying
degrees. The most important requirements
for lubricants are:
Reduction in friction and wear
Corrosion protection/noise reduction
Protection against contamination/ in-
gress of foreign matter
Cooling (primarily for oils)
Durability (physical/chemical stability)
Compatible with as many materials as
possible
Economic and environmental aspects
2.2 Selection of lubricants
SKF Lubrication Systems considers lubri-
cants to be an element of system design.
The selection of a suitable lubricant should
reasonably be made during the design of
the machine and forms the basis for plan-
ning the centralized lubrication system.
The manufacturer/operator of the machine
should preferably make the selection with
the supplier of the lubricant on the basis of
the requirements profile of the specific task.
If you have no or little experience selecting
lubricants for centralized lubrication sys-
tems, please contact SKF.
Only lubricants specified for the
product may be used (see “Technical
data” chapter). Unsuitable lubricants
may lead to failure of the product.
Do not mix lubricants. This can
have unpredictable effects on the
usability and this function of the
centralized lubrication system.
2.3 Material compatibility
The lubricants must generally be compatible
with the following materials:
Steel, gray cast iron, brass, copper,
aluminum
NBR, FKM (FPM), ABS, PA, PU

3. Overview, functional description
3.1 General
- See Figure 1
Flow sensors of series GS30XX can monitor
minimal lubricant volumes, which are gen-
erated in pulses by a metering device, on the
way to the lubrication point.
The sensors are suitable for oils and fluid
greases. Minimal lubricant volumes can be
detected in the range from 0.01 to 0.6 cm³
per metering pulse.
The variants of the GS30XX all operate
according to a calorimetric measuring prin-
ciple and differ in terms of the number and
design of their signal outputs (see Figure 3).
The sensors are not suitable for the detec-
tion of continuous lubricant flows.
3.1.1 Calorimetric principle
The process is based on the physical laws of
thermal conduction and thermal transfer in
liquids and gases. A body with a higher tem-
perature emits energy into its environment
in the form of heat. The amount of energy
transfer depends on the temperature differ-
ence and the mass flow.
3.2 Function
If the GS30XX sensors, which operate un-
der a calorimetric measuring principle (see
Chapter 3.3.1), detect a lubricant volume
occurring in pulses, the evaluation electron-
ics generate a discrete electrical output
signal for 3 seconds. The yellow LED on the
sensor lights up in the process.
The output signal can be evaluated by the
user, for example using a PLC.
Due to the calorimetric measuring principle,
the sensor element in the sensor requires
an interval time (pause) after a lubricant
pulse. During this time, the energy previ-
ously extracted from it by the evaluation
electronics is returned so that a defined
sensor sensitivity is achieved.
The interval time depends on various pa-
rameters, such as the lubricant volume, the
flow velocity, and the lubricant temperature.
The most important factor determining the
interval time is the lubricant volume flowing
past the sensor element. A small lubricant
volume draws less energy from the sensor
element than does a larger quantity of lubri-
cant. Less time is thus needed to replenish
the extracted energy.
Maintaining an interval time of 15 seconds
ensures that the sensors reliably detect a

Overview, Fig. 1
SPS
lubricant pulse across the entire applicable
temperature and quantity range.
In applications in which metered quantities
in the detection range of 0.01 – 0.10 cm3
are to be monitored, the required interval
time may in individual cases be less, result-
ing in monitoring intervals of less than 15
seconds.
If metering pulses are monitored at an in-
terval of less than 15 seconds, the interval
time between lubricant pulses that yields
reliable detection by the sensor must be de-
termined for the specific application.
3.3 Attachment
Flow sensors of series GS30XX are attached
using assembly holes located on the sensor
housing that are designed for M4 screws.
Both lubrication piping are screwed into the
sensor housing using M8x1 screw unions or
SKF quick disconnect coupling.
The flow direction of the lubricant must
be paid attention to during assembly; it is
marked by a direction arrow applied to the
housing.
The electrical connection is established ac-
cording to the wiring diagram applied to
the housing or according to the description
Chapter 6, “Assembly.”

Due to the nature of the system, the sen-
sor element located between the lubricant
inlet and the lubricant outlet in the sensor
housing is designed so that the ambient
atmosphere directly reaches the measuring
element. The electronic components are
thus exposed directly to the lubricant. Dur-
ing assembly, it must therefore be ensured
that no solid object, lubricant particles, con-
taminated lubricant or any kind of cleaning
agent touches the sensor board. This could
result in destruction of the sensor element
and thus failure of the flow sensor.
Further, it should be note that lubricants
that are corrosive or have degraded
through aging can also corrode electronic
components.
Prior to installing the flow sensor, the cus-
tomer must check the ambient and medium
influences on the sensor.
If necessary, consult SKF Lubrication Sys-
tems Germany GmbH.
The flow sensor does not require calibration.
Further:
○Connect the flow direction of the flow
sensor according to the “†“ direction ar-
row affixed to the sensor housing.
○Other units must not be damaged by as-
sembly work.
○The product must not be installed within
range of moving parts.
○The product must be installed at a suf-
ficiently large distance from sources of
heat or cold.
○Observe the IP protection class of the
product
○Maintain safety clearances and comply
with statutory regulations for assembly
and accident prevention.
○The mounting position requirements
in “Technical data” (Chapter 4) must be
observed.
